Description

TECHNICAL FIELD

[0001] The utility model relates to turbidimeter technical field, specifically is a turbidimeter. BACKGROUND

[0002] Turbidity, that is, the turbidity degree of water, is caused by trace insoluble suspended substances and colloidal substances in water, and the measurement unit used by ISO standard is FTU (turbidity unit), which is consistent with NTU (turbidity determination unit). The turbidimeter measures the turbidity of water according to this principle. The working principle of the turbidimeter is mainly based on optical principles, especially the light scattering method. When light passes through the water sample, the suspended particles in the water will hinder the straight-line propagation of light, causing light scattering. The intensity of scattered light is proportional to the number of suspended particles. Therefore, the turbidity value of the water sample can be calculated by measuring the intensity of scattered light.

During use, the inner wall of the detection groove is frequently scratched by the outer wall of different detection bottles. Dust and impurities in the air are inevitably adhered to the inner wall of the detection groove. If these dust and impurities are not cleaned, they will affect the detection accuracy of the turbidity of the sample in the detection bottle during subsequent use. UTILITY MODEL CONTENT
